A compact 550 watt slow flow RF excited CO2 laser directly attached to a Yaskawa
Motoman robot is used to cut three dimensional patterns in 1 mm thick curved steel
sheets. The quality and speed of the cutting is identical to that of cuts made with
a static laser, since movement of the laser does not degrade its mode quality in any
way. The light weight laser head is rigidly attached to the five-axis robot and is
flexibly connected to its power/gas/cooling sources. It can be manipulated through a
2r spherical angle at dynamic accelerations of up to at least (3.4g.
This laser-robot system implements the ultimate precision capability of the robot.
Its potential for manufacturing flexibility will be reviewed.
